Mr. Clean Magic Eraser's really do a wonderful job, We use it on all White MacBook's it brings back a nice , Brand New Appearance... DO NOT USE ON THE DISPLAY.. for the Display's a small bit of water on a micro fiber towel works very nicely..

I always use simple microfiber cloth for glasses - slightly "damp"

worked perfect for me

92% Rubbing Alcohol, the clear kind and paper towels on any plastic parts of the system, for glass, a microfiber cloth. Alcohol will evaporate, unlike other cleaning agents which can cause electrical shorts if it hits the wrong places, etc ... that's the reason that alcohol is used to clean logic/motherboards. (DON'T use the 50% stuff on logic boards, 92%+ only).

If you experiment with other 'cleaners' be sure to test on a small, hidden surface, but I've been using 92% alcohol since 1986 on systems without fail.

Note: for mac/pc desktop keyboards, a toothbrush dampened in a bit of ^ alcohol makes it easy to get between the keys, and simply wipe with a paper towel.
